MARTIN BOURKE, OF YOUNGSTOWN, OHIO.

FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 486,425, dated November22, 1892.

Application filed April 9,1892- fierial No. AZ8A63- (No model.)

To all whom it may concern.-

Be it known that I, MARTIN BOURKE, a citizen of the United States,residing at Youngstown, in the county of Mahoning and State ofOhio,haveinvented certain newand usefulImprovements in Sash-Fasteners;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters of referencemarked thereon.

Figure 1 of the drawings represents a perspective view showing myimproved fastener applied to the two sashes of awindow-frame; Fig. 2, asectional View thereof; Fig. 3, an end and sectional view, respectively,of the cam-thimble.

The present invention has relation to that I class of sash-fasteners forwhich a patent was granted to me June 29, 1886, No. 344,436, and isdesigned as an improvement thereon, whereby the screw-thread on the endof the bolt and the screw-threaded plate to receive the same aredispensed with and a cam device substituted, thus enabling the fastenerto operate more perfectly and decreasing the cost of manufacture, aswell as rendering the device much stronger and more durable, as thereare no screw-threads to Wear out upon the end of the bolt.

The invention consists in a fastener constructed substantially as shownin the drawings and hereinafter described and claimed.

1n the accompanying drawings, A represents a portion of the upper sashof a window-frame, and B the lower sash, both of which are of the usualconstruction.

To the side rail of the upper one of the sashes is suitably connected athimble O, which is provided in the present instance with a cam-shouldera upon its interior and upon its exterior with screw-threads b, by whichit is held in a mortise formed in the side rail. Now in order to screwthe thimble in the mortise it will be necessary to provide means forthat purpose, and thereforeI have formed or provided the thimble uponits outer end with a depression 0, diametrically opposite the groove cl,whereby a screwdriver may be used therewith, the depression and grooveserving together the same purpose as the groove in the head of a screw.Without departing from the principle of my invention it is evident thatthe thimble may be secured to the side rail of the sash in anywell-knownand preferred manner without the use of the screw-threads, and thecamshoulder may be upon the outside or exterior of the thimble insteadof the interior, which modification would serve the same purpose. Anychanges or modifications that would come Within ordinary mechanicalskill I reserve the right to make without departing from my invention.Any number of these thimbles with the cam-shoulder thereon may be usedas found desirable, so that the sashes may be firmly locked in a closedposition or opened to any height and firmly and se curely held there.

As in my former patent, the top rail of the lower sash has a bracket orguide-plate D, secured thereto by screws or other preferred means, andupon the plate is supported the short standard e, which has upon itsupper end a bearing-sleeve E to receive a bolt F, which is adapted toturn therein. This bolt has upon its outer end a thumb-piece f and uponits inner end or that portion projecting beyond the sleeve a lug g toact in conjunction with the cam-shoulder wat to draw the two sashestogether tightly against each other, so as to prevent the sashesrattling, and also prevent the air from passing into the room, and,further, to securely lock the sashes in their adjusted position, eitheropen or closed.

In the operation of the device it Will be noticed that the standard,with the bearingsleeve thereon, is capable of lateral adjustment uponthe guide-plate, so as to bring the bolt on line to register with theopening in the thimble. When this is done, the bolt is turned so thatthe lug thereon will register with the groove d in the thimble, afterwhich the bolt can be engaged with the thimble, and when said bolt isturned the lug will ride over and upon the cam-shoulder and firmly andsecurely draw the two sashes together and hold them either opened orclosed.

Having now fully described my invention,

what I claim as new, and desire tov secure by the interior cam-shoulderof the thimble, Letters Patent, issubstantially as specified.
